71 dart instrument cluster

So i just bought 71dart. the fuel and temp gauge dosent work. oil pressure light works and some of the cluster instrument lights work like turn signal light. i have alredy taken the cluster out and cleaned circuit board from corrosion and i did verify that the meters work with battery charger straight to terminals. and how can i verify if my temp sensor if working? it is 1pin.
Thanks in advance :)

Electrical is section/chapter 8, wiring diagrams are in the back of that chapter.... Make sure that you are looking at the Dart wiring diagrams and not the other models...
